## How do you solve an equation in point slope form?

Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept). Watch this video to learn more about it and see some examples.

**Which equation in point slope form passes through (- 2 4 and has a slope of 3?**

If we know that the slope of our line is 3 and the point that it is passing through is (-2,4), then we can use slope-intercept form to solve it. The formula y=mx+b.

### What is the equation in point slope form for a line that goes through 2 − 6 and has a slope of − 3 4?

Answer Expert Verified The equation that is in point-slope form for a line that goes through (2,-6) and has a slope of -3/4 is y+6=-3/4(x-2). The equation for point-slope is y-y1=m(x-x1). So just take the given info and plug it in.

**Which is the equation of a line that has a slope of 1/2 and passes through Point 2 3?**

So for this, I will be making the equation using the slope-intercept form, which is y=mx+b (m = slope, b = y-intercept). Since we have the slope, 1/2, we can just plug in (2,-3) into the equation and solve for b as such: Putting everything together, our equation is y = 1/2x – 4.

## How do I find the slope-intercept form?

Slope-intercept form, y=mx+b, of linear equations, emphasizes the slope and the y-intercept of the line.

**What is the formula for slope and y-intercept?**

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

### What is the first step in slope intercept form?

Remember, the slope-intercept formula is y = mx + b. Plug in your slope where the “m” value is, and plug in your y-intercept where the “b” is. This is the equation of the line in slope-intercept form.

**What is slope intercept form example?**

y = 5x + 3 is an example of the Slope Intercept Form and represents the equation of a line with a slope of 5 and and a y-intercept of 3. y = −2x + 6 represents the equation of a line with a slope of −2 and and a y-intercept of 6.

## How do you do slope step by step?

How To Calculate Slope

- What is Slope?
- 4 Steps to Calculate Slope.
- Step 1: Find two points anywhere on the line.
- Step 2: Count the rise (the units up or down) to get from one point to the next.
- Step 3: Determine the run (the units left to right) to get from one point to the next.
- Step 4: If possible, simplify the fraction.

**How do I calculate slope?**

To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100.

### What is a positive slope?

A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.

**How do you find the slope of a right triangle?**

The hypotenuse of the triangle (the diagonal) is the line you are interested in finding the slope of. The two ‘legs’ of the triangle are the ‘rise’ and ‘run’ used in the slope formula. Slope = rise/run.

## How do you find the slope of a curve?

The slope of a curve y = f(x) at the point P means the slope of the tangent at the point P. We need to find this slope to solve many applications since it tells us the rate of change at a particular instant. [We write y = f(x) on the curve since y is a function of x. That is, as x varies, y varies also.]

**What is slope of tangent?**

The derivative of the function at a point is the slope of the line tangent to the curve at the point, and is thus equal to the rate of change of the function at that point. We call this limit the derivative. Its value at a point on the function gives us the slope of the tangent at that point. For example, let y=x2.

### What is the formula of slope of tangent?

Finding the Equation of a Tangent Line. Figure out the slope of the tangent line. This is m=f′(a)=limx→af(x)−f(a)x−a=limh→0f(a+h)−f(a)h. Use the point-slope formula y−y0=m(x−x0) to get the equation of the line: y−f(a)=m(x−a).

**How do you find the smallest slope of a curve?**

The smallest slope is given by the minimum value of f. It’s not difficult to see that f(x) is a parabola so the minimum value is attained at the local minimum which occurs at x=0, namely at point (0,1) on the curve you have. Then minf=f(0)=−4.

## At what point is the tangent line to the curve perpendicular to the line?

The derivative of a function at a point is the slope of the tangent line at this point. The normal line is defined as the line that is perpendicular to the tangent line at the point of tangency.

**What is a minimum gradient?**

The minimum gradient of our green curve will be when its gradient is zero, so setting gives us: , so , or . This is easily visible on the above graph. To find the y-coordinate of our minimum point, we just put this value of x back into the original equation. Long story short, the minimum point is at or roughly .

### Which equation represents a line that passes through 9 3 and has a slope of 6?

Answer: The required equation of line is y=-6x-57. Where m is slope of the line. It is given that a line that passes through (–9, –3) and has a slope of –6.

**Which equation shows the point slope form of the line that passes through 3 2 and has a slope of 1 3?**

Which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of 1/3 ? The equation of a linear function in point-slope form is y – y1 = m(x – x1).

## Which points can be used to create a line with an undefined slope?

If we want to use a point to create a line with an undefined slope through , then that point must have the same x-coordinates as the given point. Since the given point, has an x-coordinate of , we check all the points that have an x-coordinate of -3.

**What is the slope of the line represented by the equation f/t )= 2t − 6?**

What is the slope of the line represented by the equation f(t)=2t−6? The slope is 2 and the y-intercept is −6.

### What is the slope of the line − 3 3?

You can also use the slope formula with two points on this horizontal line to calculate the slope of this horizontal line. Using (−3, 3) as Point 1 and (2, 3) as Point 2, you get: The slope of this horizontal line is 0.
